Heliocybe

Heliocybe is an agaric genus closely allied to Neolentinus and the bracket fungus, Gloeophyllum, all of which cause brown rot of wood. Heliocybe sulcata is the type and sole species.

==Description== Heliocybe sulcata is characterized by thumb-sized, tough, revivable, often dried, mushroom fruitbodies. The tanned symmetric cap (pileus) is up to across and radially cracked into a ray pattern of scales and ridges. The lamellae are cream-coloured, distant and serrated. The stipe is cylindrical, up to 2 cm tall and 4 mm wide, sometimes curved, and scaly towards the base, often enlarged.
